Physicists have designed a set of quantum control protocols that can make a monitored quantum process look as though time is flowing backward, forward at a different speed, or in no clear direction at ...

Irvine, Calif., April 13, 2026 — Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...
